Sequencing technologies have deeply changed our approach to the study of food microbial communities. This review describes recent exploitations of high-throughput sequencing applications to improve our knowledge of food microbial consortia. In the past 10 years, target amplicon sequencing has become routinely used in many food microbiology laboratories, providing a detailed picture of food-associated microbiota. Metagenomics and metatranscriptomics approaches are still underexploited in food microbial ecology, despite their potential to uncover the functionality of complex communities...

Kévin Duarte, Jean-Marie Monnez, Eliane Albuisson
The present study addresses the problem of sequential least square multidimensional linear regression, particularly in the case of a data stream, using a stochastic approximation process. To avoid the phenomenon of numerical explosion which can be encountered and to reduce the computing time in order to take into account a maximum of arriving data, we propose using a process with online standardized data instead of raw data and the use of several observations per step or all observations until the current step...

Life-long primary prevention interventions beginning and continuing throughout an individual's lifetime are increasingly seen as key to meeting the global healthcare challenges that accompany demographic changes - a concept referred to as "Healthy aging". In this perspective, vaccination is seen as part of a triad, together with healthy diet and exercise. Current adult vaccine coverage is lower than target vaccination rates in most developed countries, and so vaccine preventable diseases continue to present a substantial burden on health and healthcare resources, especially in older individuals...

REVIEW
Lucie Juliot
Patients with psychosis speak of an uneasy relationship with their body. Between feelings of too little and too much, for them it is a matter of trying to suture an image which is not always unified, a body which they are not always sure they have. The attentive clinician will attempt to support the solutions of each psychotic patient to maintain their body, beyond the death drive which pushes them to tear it apart.

Crystal Jing Jing Yeo, Zachary Simmons
The recent approval of edaravone by the United States Food and Drug Administration has generated a mix of hope tempered by reality. The costs of the drug, both monetarily and with regard to intensity of treatment, are high. The benefits, while modest, will be viewed through a very different lens by individuals depending on their goals of care. By virtue of our training and experience, physicians are ideally suited to understand and explain new treatments to our patients. As healthcare providers with a fiduciary responsibility to our patients, we must make sure they are fully informed about both the costs and benefits of non-curative therapies such as edaravone, and be prepared to discuss these in the context of their goals of care and potential impact on quality of life...

BACKGROUND: Most people experience low back pain (LBP) at least once in their life and for some patients this evolves into a chronic condition. One way to prevent acute LBP from transiting into chronic LBP, is to ensure that patients receive the right interventions at the right moment. We started research in the design of a clinical decision support system (CDSS) to support patients with LBP in their self-referral to primary care. For this, we explored the possibilities of using supervised machine learning...

Suree Yoowannakul, Andrew Davenport
Dialysis patients are at increased risk for muscle wasting, and time efficient screening tests are required for to allow for early detection. Creatinine kinetics have been advocated to estimate lean body mass (LBM) in peritoneal dialysis (PD) patients, and can be readily calculated in clinical practice from peritoneal dialysate effluent and urine collections. Bioimpedance is increasingly available, and we compared methods in 434 PD patients (55% men, 33.3% diabetics), mean age 55.2 ± 16.2 years. LBM was lower by creatinine kinetics (47...

Objective: We evaluated the effects of three different strategies for communicating diagnostic uncertainty on patient perceptions of physician competence and visit satisfaction. Design/Setting: Experimental vignette-based study design involving pediatric cases presented to a convenience sample of parents living in a large US city. Participants/Intervention(s): Three vignettes were developed, each describing one of three different ways physicians communicated diagnostic uncertainty to parents-(i) explicit expression of uncertainty ('not sure' about diagnosis), (ii) implicit expression of uncertainty using broad differential diagnoses and (iii) implicit expression of uncertainty using 'most likely' diagnoses...

Changpeng Lang, Yi Liu, Kunjian Cao, Shiliang Qu
An optical fiber strain sensor based on capillary-taper compensation structure was proposed. The theoretical simulation by using the finite element analysis method shows a matching condition between the capillary length and the interference-cavity length to achieve the zero temperature crosstalk. Meanwhile, the strain sensitivity can also be improved greatly at the matching condition. We then set up an insertion controller system with high accuracy to make sure the interference-cavity length can match the capillary length...

James K Stoller
Rare diseases pose particular challenges to patients who are affected, to the clinicians who care for them, and to the investigators who study their conditions. Though individually uncommon, rare diseases are common in the aggregate, with the ∼7000 described rare diseases affecting 25-30 million Americans. Challenges posed to affected individuals and their families largely regard being diagnosed; receiving optimal care; and affording disease-specific medications. Challenges facing clinicians who care for affected individuals include gaining knowledge and experience in caring for such patients, and the availability of local experts and of expert guidelines...

Todd A Linsenmeyer
This review is based on the author's Donald Munro Lecture given at the annual conference of the Academy of Spinal Cord Injury Professionals in New Orleans, LA. Indwelling catheters play an important role in bladder management following SCI for many individuals with neurogenic bladders. There is an increased risk of UTI compared to other types of bladder management with indwelling urethral catheters but not SP catheters. To minimize the risk of symptomatic UTI, the following steps are essential: prevent bladder wall distention and resulting ischemia, maintain colonization with "good" bacteria, and prevent bladder stones...

The removal of sulfapyridine (SPY) by ferrate(VI) in aqueous solutions under a broad range of reaction conditions including ferrate(VI) dosage, solution pH, natural organic matter and coexisting inorganic ions were systematically investigated and the oxidation pathway of SPY by ferrate(VI) was deeply explored. Results showed that 500 µg/L of SPY was efficiently decomposed (86%) within 1 min by 5 mg/L ferrate(VI) at pH 5.6. The increment in ferrate(VI) dosage was surely favorable for SPY removal. The best SPY degradation was achieved at pH 5...

Inflammatory bowel disorder is associated with certain pathophysiological disturbances which make established techniques of colon targeting more complex and inconsistent. Probable reason is severity of inflammation which leads to more variability in normal range of triggering factors that are being exploited for colon targeting. Influential changes in pathophysiology of intestine during inflammatory bowel disorder including Crohn's disease and ulcerative colitis both in active as well as quiescent stage have been discussed...
